- What does . shape [] do in for i in range (Y. shape [0])?
shape is a tuple that gives you an indication of the number of dimensions in the array So in your case, since the index value of Y shape[0] is 0, your are working along the first dimension of your array
- tensorflow placeholder - understanding `shape= [None,`
You can think of a placeholder in TensorFlow as an operation specifying the shape and type of data that will be fed into the graph placeholder X defines that an unspecified number of rows of shape (128, 128, 3) of type float32 will be fed into the graph a Placeholder does not hold state and merely defines the type and shape of the data to flow
- python - shape vs len for numpy array - Stack Overflow
Still, performance-wise, the difference should be negligible except for a giant giant 2D dataframe So in line with the previous answers, df shape is good if you need both dimensions, for a single dimension, len() seems more appropriate conceptually Looking at property vs method answers, it all points to usability and readability of code
- Keras input explanation: input_shape, units, batch_size, dim, etc
For any Keras layer (Layer class), can someone explain how to understand the difference between input_shape, units, dim, etc ? For example the doc says units specify the output shape of a layer
- python - PyTorch model input shape - Stack Overflow
input_shape = first_parameter size () this is for the weight size, if you save the model and open it in neuron, you would see that the weight size is the same as the input shape
- python - Keras Dense layer Output Shape - Stack Overflow
For example, output shape of Dense layer is based on units defined in the layer where as output shape of Conv layer depends on filters Another thing to remember is, by default, last dimension of any input is considered as number of channel
- r - How would one add a new shape, with both outline color and fill . . .
Donuts (hollow circles) are also intriguing What would it take to build one of these shapes and incorporate it fully into ggplot's machinery so that "it just works" whenever a user says "shape = XXX" in a ggplot call? Ideally, any shape added would have separate stroke color and interior fill color aesthetics
- python - Explaining the differences between dim, shape, rank, dimension . . .
I'm new to python and numpy in general I read several tutorials and still so confused between the differences in dim, ranks, shape, aixes and dimensions My mind seems to be stuck at the matrix
